I do not object to fixing HB_C52_STRICT functionality, as long as the
extended functionality is NOT affected and remains the default.
Another choice is an optional new library which could be built from existing
RTL sources, compiled with HB_C52_STRICT into a new alternate RTLCL52.lib
and such lib could be linked instead of RTL.lib (by those interested),
withOUT removing all extended features. IOW only Clipper RTL functions would
be reduced to strict compatability.
